- - - - Chronic inflamed hypersensitive bronchiole passages
      - Lung Cancer
        
        1/3 of all cancer deaths in the US and is associated with smoking
      - Emphesyma
        
        Alveoli enlarge as adjacent chamber break through causing chronic inflammation which promotes lung fibrosis
      - COPD
        
        Labored of difficulty breathing becomes progressively more painful
      - Chronic Bronchitis
        
        Mucosa becomes inflamed which also increases production and impairs ventilation
      - SIDS
        
        Unexplained infant death which may be cause by neural respiratory control center
- - - - To give out carbon dioxide and water into the atmosphere
      - To make sounds such as speech
      - Exhalation is breathing out
- - - - Left/Right Bronchus
      - Larynx
      - Oral Cavity
      - Nasal Cavity
      - Nostril
      - Pharynx
      - Trachea
      - Left/Right Lung
- - - - Sinuses
      - Nose
      - Nasal Cavity
      - Pharynx
      - Lower Respiratory Tract
        
        Bronchial Tree
        
        Larynx
        
        Trachea
        
        Lungs
- - - - Sum of all volumes
      - Functional Residual capacity
        
        residual volume+expiratory reserve volume
      - Expiratory reserve volume
        
        Additional air forced out during maximum expiration
      - Residual volume
        
        Amount of air left in aveoli after forrced expiration
      - Tidal Volume
        
        Air moved in one respiration
      - Inspiratory reserve volume
        
        Additional air taken in during maximal inhalation
      - Dead Space Volume
        
        Air remaining in conducting zone
      - Inspiration Capacity
        
        tidal volume+inspiratory reserve volume
      - Vital Capacity
        
        inspiratory reserve volume+ tidal volume+expiratory reserve volume
      - Major Functions of Respiratory System
        
        Gas exchanges between blood and external environment
        
        Passageways to lungs purify,warm,and humidify the incoming air
      - Breathing Mechanism
        
        Expiration
        
        Flow of air out of the lungs
        
        Inspiration
        
        Flow of air into the lungs
        
        Respiration
        
        Entire process of exchanging gases between atmosphere and body cells
        
        Pulmonary Ventilation
        
        Movement of air in the Lungs
- - - - Wider,shorter, and straighter than the left bronchus
      - Right Lung
        
        2 lobes
      - Left Lung
        
        3 lobes
      - Left Primary Bronchus
        
        Longer,thinner, and crooked than the right bronchus
- - - - occurs in the lungs where oxygen diffuses into the blood and carbon dioxide diffuses into the alveolar air.
      - Internal Respiration
        
        occurs in the metabolizing tissues, where oxygen diffuses out of the blood and carbon dioxide diffuses out of the cells
